Ekey made a script for that, but it's useless because the game simply freezes indefinitely upon loading the repacked files.

But like I said,

SergeantJoe wrote:Repacking isn't necessary, simply extract the files to ".../SleepingDogs/Data/" and if the game can't find the BIG file then it'll load those instead. HUGE thanks to Chipicao for figuring that out.
However, the game crashes instantly with all of them except for CharactersHD and Animation since the unpacker doesn't assign names to vital files.

I copied the filenames from the DE unpacker into the SD unpacker, and now Characters.BIG has only 5 unknown files instead of 70+!

Problem is they're all empty. This means that there are several model.perm.bins that are missing their their .temp.bin files, and the game still crashes trying to load them. I'll have to go through the list and check every one.
